INTRODUCTION

The Gwinnett County Board of Commissioners, Department of Transportation, Pre-Construction

Division invites you to submit a proposal responsive to the items outlined in this request for

proposals to provide construction document development for a new interchange on I-985 at

Thompson Mill Road. Award will be made on the basis of the criteria as outlined in this proposal

document.

Gwinnett County is a suburban county of with a population of about 1,000,000 located along I-85

approximately 20 miles northeast of downtown Atlanta. It is the second most populous county in

Georgia and has the third highest per capita income in the state. The unparalleled growth

experienced by Gwinnett County over the past twenty years has greatly increased the demand for new

recreational and transportation facilities in the County.

With northern Gwinnett County experiencing rapid population and traffic growth, SR 20 serves as the

sole interchange on the I-985 corridor. The I-985 at SR 20 interchange is experiencing high levels of traffic

congestion and is operating below preferred levels of service. Current crash and injury rates on I-985

and SR 20 exceed the statewide average rates when compared to similar type roadways.

As one of the prominent east-west routes of travel in this region- Thompson Mill Road provides

commuters passage to and from SR 13/Buford Highway to access local public, commercial, and

residential amenities. The purpose of providing access ramps to Thompson Mill Road at I-985 is

to reduce traffic congestion on the SR 20 Interchange; reduce the frequency and severity of crashes

on SR 20 and the I-985 mainline; reduce the queuing of traffic on the I-985 northbound auxiliary lane

and improve east-west mobility in northern Gwinnett. An Interchange Justification Report

completed by GDOT Office of Planning in 2021 will be included with this solicitation for reference.

This project consists of the design and development of construction documents for a new three

quadrant partial cloverleaf interchange configuration with a northbound loop off-ramp on I-985 at

Thompson Mill Road. This improvement would provide full access to and from I-985 northbound

and southbound at the new interchange with Thompson Mill Road.

This project is funded with federal funds administered by Georgia Department of Transportation

(GDOT) and with local funds from the County Special Purpose Local Option Sales Tax (SPLOST)

program. Therefore, the consultant and/or sub-consultants must be pre-qualified by GDOT
